"Hubski is an online pub with creative and thoughtful people belly-up at the bar of reason and sanity."
The community thought that "belly-up" sounded kind of like a dead fish and suggested other wording, but that definition has stuck with me.
Today in a face-to-face discussion with forwardslash we were expressing our relief at being with someone (each other) who required no explanation of Hubski. This led to sloganizing a little and we came up with
"Some websites are just people shouting into the void. On Hubski, there is no shouting. And there is no void. Hubski - a thoughtful web."
What do y'all think? Edits welcome.
